Already owning Accuphase kit, I had an idea of what to expect from Luxman gear... as said above, second to none build quality and the two Company's sound signature are similar too, so I was a little concerned about adding to the already rich tonal balance of the amps, worried it might be a bit overkill.
I needn't have worried. It's like the soundstage has been given a polish, giving an even more vivid sense of depth and detail and my main worry was how the base would be affected... no problem at all, tighter if anything.
Also, vocals are more fullsome, more like my old Class A Sugden.
For those of you who like their string sections, you will be astonished how good they sound.
A beautifully tonally balanced DAC... don't get me wrong though, for anyone looking for a great DAC under the 1K mark, I would still recommend the RME ADI2 in a heartbeat.
Only had the machine on 24 hours so far, so once it's got more time stocked up could well sound even better, not sure how though!
